Polish up POC Implementation for v0.1.0

[missBerg]

Depends on #13

@mathetake - please add more information here

so the plan is to merge gradually while polishing it. Even though I want to wait for the design doc #16, I will start adding the impl as soon as possible once the repo setup (like container publish etc) since the design won't change that much at this point and it will serve more of an informational purpose for anyone coming in here for the first time. It will start with the API definition PR (#13) as discussed, but little by little - not with the giant single PR.

Sounds good @mathetake
